Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a pressure-resistant and tensile-resistant pen wire harness. Background Technology

[0002] A laptop wiring harness is a key component used in laptops to ensure their normal operation. It not only delivers stable power to components such as the battery, motherboard, and hard drive, but also efficiently transmits signals to enable data interaction such as display images and keyboard input. With its high precision, high reliability, strong anti-interference capabilities, and thin and light design, it is cleverly adapted to the compact space of a laptop and withstands the test of daily use scenarios such as opening, closing, and moving. It is the "nerve network" that enables the coordinated operation of various components inside the laptop.

[0003] Currently, in order to meet the trend of thinner and lighter laptops, the power cable harnesses used in laptops use thinner wires without affecting performance. However, the thinner wires also reduce the tensile and compressive strength of the power cable harness, making it prone to breakage when subjected to external pulling and squeezing. Therefore, we propose a pressure-resistant and tensile-resistant power cable harness. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant and tensile-resistant laptop wire harness, which has the advantages of improving the pressure resistance and tensile strength of laptop wire harnesses, effectively preventing wire harness breakage during pulling and compression, and extending the service life of the wire harness. It solves the problem that in order to meet the current trend of laptops becoming thinner and lighter, the laptop wire harnesses used in these harnesses use thinner wires without affecting performance. However, the thinner wires also lead to a decrease in the tensile and compressive strength of the laptop wire harness, making it prone to breakage when subjected to external pulling and compression.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-resistant and tensile-resistant pen wire harness, comprising a first connecting terminal, a thermally conductive silicone sleeve, and a second connecting terminal. Two flexible flat wire harnesses are arranged from top to bottom between the first and second connecting terminals, with both ends of the two flexible flat wire harnesses fixedly connected to the inner sides of the first and second connecting terminals, respectively. A thermally conductive silicone spacer is provided between the two flexible flat wire harnesses. A plurality of reinforcing wires are equidistantly fixedly installed inside the thermally conductive silicone spacer, with both ends of the reinforcing wires fixedly connected to the inner sides of the first and second connecting terminals, respectively. Both ends of the thermally conductive silicone sleeve are fixedly connected to the inner sides of the first and second connecting terminals, and both flexible flat wire harnesses and the thermally conductive silicone spacer are located inside the thermally conductive silicone sleeve.

[0006] Preferably, the upper and lower surfaces of the thermally conductive silicone pad are provided with a plurality of accommodating grooves at equal intervals, and the flexible flat cable bundle contains a plurality of wires arranged side by side, each wire corresponding to an accommodating groove, and the wire is located inside the accommodating groove.

[0007] Preferably, the top of the inner wall of the thermally conductive silicone sleeve and the top of the inner side are provided with several raised strips at equal intervals, and the flexible flat cable harness contains multiple wires arranged side by side, with the raised strips located between two adjacent wires.

[0008] Preferably, both the first and second connecting terminals are provided with sealing rings on their outer surfaces. When the first and second connecting terminals are connected to the pin header terminals on the laptop, the sealing rings are compressed and thus provide a sealing effect.

[0009] Preferably, a fixing ring is fixedly sleeved on the outer surface of both the first connecting terminal and the second connecting terminal near the inner side of the sealing ring, and the fixing ring plays a limiting role in the sealing ring.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting a first connecting terminal, a second connecting terminal, a flexible flat cable harness, a thermally conductive silicone pad, a reinforcing wire, and a thermally conductive silicone sleeve, achieves the effect of improving the pressure resistance and tensile strength of the wiring harness used in laptops, effectively preventing the wiring harness from breaking under tension and compression, and extending the service life of the wiring harness. The flexible flat cable harness is connected to the device in the laptop through the first and second connecting terminals. The flexible flat cable harness is wrapped in a thermally conductive silicone sleeve, and the two flexible flat cable harnesses are also separated by a thermally conductive silicone pad, which plays a buffering role for the flexible flat cable harness under compression, improving pressure resistance. At the same time, it can also effectively transfer the heat of the flexible flat cable harness, improving the heat dissipation effect of the flexible flat cable harness. The reinforcing wire improves the connection strength between the flexible flat cable harness and the first and second connecting terminals, making the flexible flat cable harness less prone to breakage under tension, thus improving tensile strength.

[0012] 2. By setting a sealing ring and a fixing ring, this utility model achieves the effect of sealing the connection between the first connecting terminal and the second connecting terminal. When the first connecting terminal and the second connecting terminal are connected to the pin header terminal on the laptop, the sealing ring and the outer shell of the pin header terminal come into contact and are squeezed, thus achieving a sealing effect.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0019] like Figures 1-4 As shown, this utility model proposes a pressure-resistant and tensile-resistant pen wire harness, including a first connecting terminal 1, a thermally conductive silicone sleeve 4, and a second connecting terminal 5. Two flexible flat wire harnesses 7 are arranged from top to bottom between the first connecting terminal 1 and the second connecting terminal 5, with both ends of the two flexible flat wire harnesses 7 fixedly connected to the inner sides of the first connecting terminal 1 and the second connecting terminal 5, respectively. Each flexible flat wire harness 7 is composed of multiple wires arranged side-by-side, and the insulation layer on the outer surface of the wires is wrapped around the outer surface of the wires by extrusion molding. A thermally conductive silicone spacer 6 is provided between the two flexible flat wire harnesses 7. The upper and lower surfaces of the thermally conductive silicone spacer 6 are each equally spaced with several receiving grooves 9 to accommodate... The grooves 9 and the wires correspond one-to-one. The wires are located inside the grooves 9. Several reinforcing wires 8 are fixedly installed at equal intervals inside the thermally conductive silicone pad 6. The two ends of the reinforcing wires 8 are fixedly connected to the inner sides of the first connecting terminal 1 and the second connecting terminal 5, respectively. The two ends of the thermally conductive silicone sleeve 4 are fixedly connected to the inner sides of the first connecting terminal 1 and the second connecting terminal 5, respectively. The two flexible flat cable bundles 7 and the thermally conductive silicone pad 6 are all located inside the thermally conductive silicone sleeve 4. Several raised strips 10 are provided at equal intervals on the top of the inner wall and the top of the inner surface of the thermally conductive silicone sleeve 4. The raised strips 10 and the thermally conductive silicone sleeve 4 are integrally formed. Each raised strip 10 is located between two adjacent wires.

[0020] In use, the flexible flat cable harness 7 is connected to the device in the laptop computer through the first connecting terminal 1 and the second connecting terminal 5. The flexible flat cable harness 7 is wrapped with a thermally conductive silicone sleeve 4, and the two flexible flat cable harnesses 7 are also separated by a thermally conductive silicone spacer 6. This cushions the flexible flat cable harness 7 when it is compressed, improves its pressure resistance, and effectively transfers the heat of the flexible flat cable harness 7, thus improving its heat dissipation effect. The reinforcing wire 8 improves the connection strength between the flexible flat cable harness 7 and the first connecting terminal 1 and the second connecting terminal 5, making the flexible flat cable harness 7 less prone to breakage when pulled, thus improving its tensile strength.

A fixing ring 3 is fixedly sleeved on the outer surface of both the first connecting terminal 1 and the second connecting terminal 5 near the inner side of the sealing ring 2. The fixing ring 3 plays a limiting role for the sealing ring 2.

[0022] In this embodiment, when both the first connecting terminal 1 and the second connecting terminal 5 are connected to the pin header terminal on the laptop, the sealing ring 2 and the outer shell of the pin header terminal come into contact and are squeezed, thus achieving a sealing effect.
